Answer:
If Earth were to change its orbit – maybe because the sun somehow disappeared or another, larger object entered the solar system and exerted a stronger pull – it would very likely mean the end of life as we know it. Without any orbit, Earth would likely go crashing directly into the sun.

Explanation: The hail begins as rain and freezes as it falls down to the surface.
The Value of K is less than 1. K is equal to 0.44.
- The balanced chemical equation for the reaction is
HDO+H2 HD + H₂O
- At equilibrium, the number of moles of reactants is greater than products. This is a reactant-favored reaction so the equilibrium constant K must be less than one.
- The equilibrium constant is the ratio of product of concentration of products to that of concentration reactants with coefficients raised to their power. Considering each molecule depicted is 0.1M.
K = ([H2O][HD])/([HDO][H2])
K = ([0.2][0.2])/([0.3][0.3])
K = 0.44

<h3><u>Answer;</u></h3>
A. have a full outer electron shell
<h3><u>Explanation</u>;</h3>
- Noble gases are elements that are found in Group 18 of the periodic table. They include, Neon, Argon, Krypton, Xenon, etc.
- <em><u>The outer shell of valence electrons is considered to be “full” in noble gases, giving them little tendency to participate in chemical reactions. This means they have an octet configuration.</u></em>
- They are all monatomic gases under standard conditions, including those with larger atomic masses than many other elements that are solids under standard conditions.
